A method of assessing performance of a seat is provided. The method comprises identifying a number of critical seats for testing from a layout of passenger accommodation and building a computer simulation model, following a building block approach, for each identified critical seat. A number of loads are tested on each simulation model. Critical seats are selected for physical testing from simulation model test results according to a specified criteria assessment matrix.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method of claim 2, wherein the airbag is deployable from a bulkhead in front of an identified critical seat in the layout of passenger accommodation.
7. The method of claim 1, wherein analyzing interface loads and mounting cross-beams of the baseline seats comprises analyzing load forward and down conditions for different occupancy conditions including fully occupied, partially occupied, and unoccupied.
8. The method of claim 1, wherein analyzing interface loads and mounting cross-beams of the baseline seats comprises removing from consideration non-critical parts with static loads below a specified threshold.
10. The method of claim 1, wherein the criteria assessment matrix relates a number of test cases to a number of structural seat criteria and a number of occupant safety criteria.
23. The system of claim 22, wherein the airbag is deployable from a bulkhead in front of an identified critical seat in the layout of passenger accommodation.
27. The system of claim 21, wherein analyzing interface loads and mounting cross-beams of the baseline seats comprises analyzing load forward and down conditions for different occupancy conditions including fully occupied, partially occupied, and unoccupied.
28. The system of claim 21, wherein analyzing interface loads and mounting cross-beams of the baseline seats comprises removing from consideration non-critical parts with static loads below a specified threshold.
30. The system of claim 21, wherein the criteria assessment matrix relates a number of test cases to a number of structural seat criteria and a number of occupant safety criteria.
